I want to synchronize the test manager with GitHub so that I can directly pull test case updates from the GitHub repository into the test manager. Alternatively, I would like to set up an auto-backup from the test manager to the GitHub repository, so that any updates made to the test cases in GitHub will automatically appear in the test manager.
Welcome to the community
test cases have to be published for test manager to recognize there is no github integration as such
you can try and create cicd pipelines to push the test cases when updated on github
cheers
